Video surveillance at the site captured images of an alleged suspect and police released them Monday morning, asking for help identifying the man.

On Monday afternoon, a man "fitting the description of the suspect" turned himself in at the RCMP detachment in Three Hills.

"In our opinion, the suspect voluntarily turning himself in is the best possible outcome to this event that has been an unsettling start to the new school year," the school said on its website Monday afternoon.

The school says victim services and local counselling professionals were made available to students. Classes begin at the institute on Tuesday.

Three Hills is a town in central Alberta located about 90 km northeast of Calgary.
